AL-KO Hydraulic Bleed Nipples
AL-KO Hydraulic Bleed Nipples (also known as bleed screws) are critical replacement components for AL-KO hydraulic disc brake calipers.
Engineered to withstand the high-pressure conditions of caravan and trailer braking, these fittings let technicians and owners purge air pockets from the hydraulic lines.
Each nipple features a precision-machined tapered seat to ensure a reliable, leak-free seal when fully tightened, protecting your system from fluid loss and maintaining responsive braking performance.

Frequently Asked Questions (FAQ)
Q: How tight should I crank down the bleed nipple after flushing the brakes?
A: Bleed nipples feature soft tapered tips that seal with minimal force. Tighten them firmly using a hand spanner until they seat cleanly against the caliper body. Avoid excessive force or long leverage bars, as over-tightening can easily snap the threaded neck inside the caliper housing.
Q: Can I replace a rusted steel bleed screw with a marine stainless steel version?
A: Yes. Upgrading to marine-grade stainless steel bleed nipples is highly recommended, especially for boat trailers frequently exposed to saltwater environments, as it prevents rust from seizing the threads.
Q: What should I do if brake fluid leaks out from around the threads while bleeding?
A: Minor fluid seepage around the external threads is completely normal when the nipple is loosened during active pumping. However, if fluid continues to seep from the tip or threads after you fully close and tighten the screw, the internal tapered seat may be damaged, meaning you’ll need to replace the nipple entirely.
Q: How do I safely clear a clogged bleed nipple?
A: Unthread the nipple completely from the caliper first. Use a fine piece of wire or a small drill bit by hand to clear dried mud or debris out of the centre channel, then blow clean air through it before reinstalling. Never try poking wire down the hole while it is still attached to an open caliper loop.
